1 Dehumidifier capacity is generally measured by how many pints of water a unit removes from the air in 24 hours. 2  A mini-dehumidifier (1-10 pints) for a bathroom, closet or under a counter usually costs $40-$70.
A dehumidifier is generally a household appliance which reduces the level of humidity in the air, usually for health or comfort reasons, or to eliminate musty odor.y their operation, dehumidifiers extract water from the conditioned air. This collected water (usually called condensate) is not normally used for drinking, and is often discarded. Some designs, such as the ionic membrane dehumidifier, dispose of excess water in a vapor rather than liquid form.
